BIAS-CUTTER.

SPECIFICATION forming part of Letters Patent No. 234,476, dated November 16, 1880.

Application filed July 1, 1880.

T 0 all whom it may concern Be it known that I, WILLIS F. HOOD, of Deerfield, county of Lenawee, State of Michigan. have invented a new and useful Improvement in Bias-Gutters; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a new and useful improvement in bias-cutters, or machines for cutting fabrics on the bias, as is more fully set forth and explained in the following specification, and pointed out in the claims.

. In the drawings, Figure 1 is a plan view of a device embodying my invention. Fig. 2 is a side view of the same. Fig. 3 is a cross-section of the same.

The object of my invention is to furnish to manufacturers of various articles requiring goods to be cut on the bias a neat, comely, and cheaply-constructed machine by which the cutting up of goods into strips of different width may be accomplished in a rapid and convenient manner.

The invention consists in a folding-bar, A A, with a movable or sliding block or handle, a, on the upper leaf, A, the said handle ahaving a sharp blade, 0, projecting through a slot, E, in the upper leaf, A, sufficiently far into a slot, E, in the lowerleaf, A, to cut any material which may be placed between them.

I The device is operated by sliding the handle along the top bar, A.

In the lower leaf of the folding-bar A, and passing diagonally through it, is a sliding bar, (3, adjusted at an angle of forty-five degrees with the folding-bars. A cross-head, O, is secured to the end of the sliding bar, adjusted so as to be exactly parallel with the line of cut of the knife.

The sliding bar isgraduated so as to adjust the gage O to any required width of strip to be out, and is retained at any desired width by a hook, D, secured to the lower leaf, and engaging with suitable holes, d,in the sliding bar 0.

Situated at the open end of the lower leaf of the folding-bar A is a spud, G, projecting into a socket, g, in the upper leaf of the fold- (No model.)

graduated bar be adjusted at any other an gle than forty-five degrees, if so desired; but as this angle forms a true bias it is the one usually employed.

The operation of the device is as follows: The graduated bar is first adjusted so as to cut the fabric in strips of the desired width. The material to be cut is then laid along the edge of the graduated bar in order to secure the first bias-cut, and the subsequent cuts may I be obtained by placing the material against the head of the gage. The upper leaf is closed over the material, its position being found by placing the spud in its socket, which serves to hold it securely, and the knife then drawn rapidly across the goods. The knife may be operated in either direction.

' lVhat I claim is- 1. In a bias-cutter, the combination, with a folding-bar and a knife, of an independent bar located angularly to the folding-bar, and provided with a cross-head adapted to serve as a gage, substantially as set forth.

2'. In a bias-cutter, the combination, with a folding-bar and a knife, of an independent movable bar provided with a cross-head which serves as a gage, said movable bar being adapted to adjust its cross-head to and from the folding-bar, substantially as set forth.

3. In a bias-cutter, the combination, with a folding-bar and a knife, of a sliding bar provided with a cross-head, and adapted to have longitudinal movement in a line angular to the folding'bar, substantially as set forth.

4. In a bias-cutter, the combination, with a folding-bar and a knife, of a sliding bar provided with a cross'head, and adapted to have movement in a line angular to the folding-bar, and a fastening device which looks the slidin g bar in adjusted position, substantially as set forth.

5. In a bias-cutter, the combination, with a folding-bar and a knife, of an independent movable bar provided with a cross-head located parallel with the path of the knife, and adapted to be maintained in such parallelism as the movable bar adjusts it to or from the folding-bar, substantially as set forth.

6. In abias-cutter, the combination, with a folding-bar and a knife, of a diagonal graduated bar provided with a cross-head parallel with the path of the knife, said bar being adapted to have longitudinal sliding movement, and to be secured in adjusted position, substantially as set forth.

7. In a bias-cutter, the combination, with a folding-bar having its lower leaf provided with a transverse opening, of a sliding bar fitted in the latter, and provided with a crosshead, substantially as set forth.

8. In a biascntler, the combination, with a folding-bar having its lower leaf provided with an opening crossing it at a suitable angle, of a sliding bar fitted in said opening and provided with a cross-head, said lower leaf being provided with a hook which engages with a longitudinal series of holes formed in the sliding bar, substantially as set forth.

9. In a bias-cutter, the combination, with the upper leaf of a folding-bar, of a knifeblock secured thereto against vertical displacement, and. adapted to have free longitudinal adjustment thereon, substantially as set forth.

10. In a bias-cutter, the combination, with the upper leaf of a foldingbar, of a knifeblock connected thereto, substantially as described, whereby said knife-block is maintained throughout its longitudinal movement in constant bearing upon the upper leaf, substantially as set forth.

11. In a bias-cutter, the combination, with the upper leaf of a folding-bar, of a knifeblock secured thereon by longitudinal mortiseand tenon connection, substantially as set forth.

12. In a bias-cutter, the combination, with a folding-bar having its upper leafprovided with an upright L-shaped tenon extending lengthwise therewith, of a knife-block having its under surface prot'ided with a corresponding mortisein which said tenon fits, substantially as set forth.

In testimony whereof I sign this specification in the presence of two witnesses.
